In this activity, learners predict where a ball will go after it bounces off another object. Learners discover that the motion of objects is predictable based on laws of motion.

This activity (on pages 35-43) lets learners analyze a "herd of elk" to detect the spread of a bacterial disease called brucellosis.

In this math lesson, learners learn how to construct stem and leaf plots. Learners first estimate the number of drops of water that will fit on the head of a penny.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

This activity introduces the idea that computer scientists measure information by how "surprising" a message is.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners estimate risks associated with different events and compare their estimates to the real possibilities.

In this sorting activity, learners play a game in which they try to identify the largest number of differences between two objects.

In this activity, learners use their understanding of probability to guess which color will be drawn from a bag.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this activity, learners help a poor cartographer color in the countries on a map, making sure each country is colored a different color than any of its neighbors.

This activity (on page 2 of the PDF under SciGirls Activity: Forecasting) is a full inquiry investigation into meteorology and forecasting.

In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.

In this math lesson, learners extend their understanding of basic probability concepts as they learn to name all of the possible outcomes of an event as well as ways to express the likelihood of such

In this calculus activity, learners use a classic problem of geometrical probability to find an important mathematical constant (pi).

In this math game (Page 14 of the Are You Game? PDF), learners determine the probability of getting an even versus an odd product using the numbers on a regular deck of cards.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

This activity (on page 2 of the PDF under SciGirls Activity: Tug O' War) is a full inquiry investigation into tug-of-war physics. Groups of learners will test two tug-of-war strategies.

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
